Increased prices on fuel and the general focus on the reduction of CO2-emissions draws attention to high-efficiency production of heat and electricity and use of environment-friendly fuels.

Efficient and environment-friendly production

COWI offers all services when it comes to the establishment of efficient and environment-friendly production of heat and electricity for both domestic and industrial use.

We have more than 50 years’ experience in the district heating sector, ranging from systems based on oil-fired boilers and coal-fired boilers to gas-fired combined heat and power (CHP) plants.

Today the focus is mainly on renewable sources both for heat and electricity.

Optimisation of heat supply

An integral part of our work is often to optimise heat supply to local conditions. This results in the lowest possible average cost for heat.

We use modern simulation tools and long-term budget models to find the best mix between base load units with low operational (fuel) costs and peak load units with low investment costs.

COWI has developed a tool for analyses of the operation of biomass-fired boilers.

Full service range

COWI offers full services ranging from initial investigation through feasibility analyses, design, tendering and supervision to optimised operation and maintenance of all types of production units.

A key focus area in addressing the environmental problems of the world, specifically in relation to air pollution, is the environmental and technical performance of the power and heating plants. Improved energy efficiency is linked directly to improved environmental and financial performance.

Further investments in environmental upgrading and efficiency improvements are major objects for the international emission trading schemes and systems, such as the EU Emission Trading Scheme (ETS) and the Kyoto Protocol.

COWI provides consultancy services within all project phases of the project cycle, i.e. feasibility studies, conceptual design, tendering and supervision.

Environmental upgrading

Internationally, coal is and will continue to be a primary energy resource for power and heating plants.

COWI is involved in all aspects of environmental upgrading of thermal power plants (TPPs), including air pollution, ash and slag handling and depositing, water and wastewater utilisation and treatment.

Energy efficiency

Energy efficiency improvements cover a wide range of possible measures from pre-treatment of coal over the energy conversion efficiency in boilers, turbines and auxiliary equipment to utilisation of waste heat for either heat or cooling purposes.

Emission trading

The international emission trading is becoming more and more important along with the implementation of the various international agreements within this field as for example the EU emission trading scheme and the Kyoto Protocol.
